EDWARD J. DOLAN, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR, BY MESNEASSIGNMENTS, TO THE ACETYLENE HOUSE LIGHTING COMPANY, OF WEST VIRGINIA.

BURNER FOR BURNING RICH GASES, ESPECIALLY ACETYLENE GAS.

SPECIFICATION forming part of Letters Patent N 0. 595,848, datedDecember 21, 1897.

Application filed April 2 9 1 89 7.

To all whom it may concern,-

Be it known that I, EDWARD J. DOLAN, of Philadelphia, in the State ofPennsylvania, have invented a new and useful Improvement in Burners forBurningRich Gases, especially Acetylene Gas, of which the following is afull, true, and exact descriptiomreference being had to the accompanyingdrawings.

This invention relates to an. improved burner for burning gases rich inhydrocarbon, and especially for burning acetylene gas, its object beingto produce practically a smokeless flame and a burner which in practicewill not become choked or clogged by dep0sited carbon. In accomplishingthis result I mingle or surround the gas to be consumed with a suitableamount of air before such gas is brought to the kindling temperature orpoint of combustion.

In my drawings similar letters refer to similar parts.

My invention will be readily understood from the accompanying drawings,in which Figure 1 is a vertical elevation of my improved burner, in partbroken away; Fig. 2, a cross-section through Fig. 1 at right angles tothe view shown in Fig. 1, and Fig. 3 a plan view of the top of theburner. A represents any suitable standard communicating by suitablegas-passages with the gas-outlets B. These outlets are inclined towardeach other at such an angle as that the jets will meet at or immediatelyabove the top of the burner, where, impinging upon each other, they forma flat flame in the wellknown manner. They are located at the bottom ofor in transverse passages parallel With the direction in which the jetis inclined. The efiect of this arrangement is that air enters at theoutside of these passages O and surrounds the jet of gas, which,however, is

not kindled until it escapes from or passes above the upper surface D ofthe burner. The result of this seems to be that the gas is surrounded onall sides with a body of air, which prevents its immediate contact withSerial No. 634,376. (No model.)

the burner-body until it has passed above the surface of the burner. Inorder to supply an additional amount of air, I also cut a transversepassage E at right angles to the passage 0, and air entering throughthis channel tends to force or raise the flame upward at the center. Asshown, these channels may be all arranged in a suitable block of any ofthe materials ordinarily employed for making gas-tips. I do not limitmyself, however, to this specific arrangement; nor do I regard thechannel E as an essential part of my invention, though it is beneficial.

WVhat I claim as my invention, and desire to secure by Letters Patent,is

1. The combination in a gas-burner of two gas-jets inclined toward eachother and located at or near the bottom of a horizontal slot,substantially as described.

2. The combination in a gas-burner of two gas-jets inclined toward eachother and located at or near the bottom of a horizontal slot, and havingan opening to the atmosphere at or about the level of theburner-openings, substantially as described.

3. The combination in a gas-burner of two jets inclined toward eachother and located at or near the bottom of a horizontal slot, and atransverse slot intersecting the first slot at or about its middle,substantially as described.

4. The combination in a gas-burner of two jets inclined toward eachother and'located at or near the bottom of a horizontal slot, and atransverse slot intersecting the first slot at or about its middle, bothof said slots having openings to the atmosphere at about the level ofthe burner-openings, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

EDWARD J. DOLAN.
